Re: Curved Shooter help

Do you support the end of the CIM shaft? We had concern that the bearing in the CIM (if unsupported) would degrade from the side load of the disc going through the shooter. Has anyone had issues with that?

It would save weight and complexity if we could do a direct drive.

It looks like your Delrin (or other material) across the end of the shooter slopes down from the sliding surface towards the wheel? Is this because the disc when compressed climbs the outside sliding surface?

What area of the disc should contact what surface of the wheel? It looks like the bottom 1/2" in of disc edge is contacting below the center line (highest point) of the wheel. Is that correct?

What is the purpose of the plastic post just in front of the wheel?


Yes, the smooth surface is supported by an aluminum wall on the back. We support it with L aluminum brackets. It needs to be pretty rigid. There can't be much flex at all

The only reason we angle it was to make sure the frisbee didn't curve on the flight pattern. When you increase the angle when it comes out, it doesn't curve as much when flying through the air. We are shooting full court so that is the reason we wanted that.

Think of a shotgun. The more accurate shotguns have a longer barrel to keep the bullet from moving much when it comes out. The is exactly what we are doing. That as a short barrel so the frisbee stays as straight as possible.
